FIELD OF THE INVENTION

The present invention relates to an intelligent cleaning robot, and in particular, to an intelligent cleaning robot that enhances dirt suction.

BACKGROUND OF THE INVENTION

A conventional intelligent cleaning robot includes a housing, a rotatable brush assembly and a vacuum dust suction apparatus. The rotatable brush assembly includes a rotatable brush frame mounted at the bottom of the housing. The rotatable brush frame has an accommodating cavity. The accommodating cavity has an opening at the bottom of the housing. Two rotatable brushes are accommodated in the accommodating cavity and are both partially exposed from the opening. The two rotatable brushes rotate in opposite directions. The vacuum dust suction apparatus includes a dust suction conduit, a dust collecting box and an impeller. One end of the dust suction conduit is in communication with the accommodating cavity, and the other end of the dust suction conduit is in communication with the dust collecting box. A gap exists between the two rotatable brushes, and dust and crumbs are sucked into the dust suction conduit through the gap. According to the principle of vacuum dust suction, with a given amount of air passing through the impeller per unit time, if the size of an air inlet of the impeller is small, an air flow velocity at the air inlet is high, and correspondingly, a suction force at the air inlet is large, while if the size of the air inlet of the impeller is large, the air flow velocity at the air inlet is low, and correspondingly, the suction force at the air inlet is small. Two rotatable brushes of the intelligent cleaning robot are accommodated in the same accommodating cavity, which leads to a relatively large size of the accommodating cavity, that is, the opening is relatively large. Therefore, the air flow velocity in the accommodating cavity is low, and as a result, the suction force in the gap between the two rotatable brushes is relatively small, which weakens the capability of the intelligent cleaning robot of sucking up dust and crumbs from the floor below the rotatable brushes.

Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

SUMMARY OF THE INVENTION

In one aspect, the present invention is directed to an intelligent cleaning robot that enhances dust suction.

In one embodiment, an intelligent cleaning robot for automatically cleaning dust on the floor includes a housing, a floor brush assembly mounted in the housing, and a dust suction apparatus mounted in the housing. The floor brush assembly has a first accommodating cavity and a second accommodating cavity. A partition plate separates the first and second accommodating cavities. A gap exists between a bottom edge of the partition plate and the floor. A first rotatable brush and a second rotatable brush are correspondingly accommodated in the first and second accommodating cavities respectively. The first and second rotatable brushes are exposed from the bottom of the housing. A slit for dirt to pass through is formed between the first rotatable brush and the partition plate. The dust suction apparatus has a dust suction conduit and a dust collecting box. One end of the dust suction conduit is in communication with the first accommodating cavity, and the other end of the dust suction conduit is in communication with the dust collecting box. When the intelligent cleaning robot cleans the floor, the first and second rotatable brushes rotate in opposite directions. The rotation of the first rotatable brush makes dirt enter the dust suction conduit through the slit, and the rotation of the second rotatable brush makes dirt enter the slit through the gap.

In one embodiment, the second rotatable brush has an elastic tube, multiple blades protrude outward in a radial direction on an outer surface of the elastic tube, and the height of the blades is less than that of the gap.

In one embodiment, the partition plate is provided with a compliance portion at a bottom end thereof, the compliance portion leans towards the second rotatable brush, and the gap is formed between the compliance portion and the floor.

In one embodiment, the first rotatable brush has a first rotating shaft, the second rotatable brush has a second rotating shaft, and the first and second rotating shafts are in a same horizontal plane.

In one embodiment, a diameter of the first rotatable brush is equal to a diameter of the second rotatable brush.

In one embodiment, the first and second rotatable brushes each have a rigid driving shaft, and a section of the rigid driving shaft is not in a perfectly circular shape.

In one embodiment, an elastic tube is sleeved over the rigid driving shaft, and an elastic material is filled between the elastic tube and the rigid driving shaft.

In one embodiment, the intelligent cleaning robot further includes two side brushes. Each of the side brushes has a rotating seat, and at least one bristle body is extended downward in a protruding manner from the rotating seat. A mounting surface is formed in a recessed manner upward on each of two sides of the bottom of the housing. A mounting slot is further provided in a recessed manner on the mounting surface. The rotating seat is mounted in the mounting slot in a fitting manner, and a bottom surface of the rotating seat is in a same plane as the mounting surface.

In one embodiment, the dust suction apparatus has a frame mounted in the housing. The frame is provided with a placement slot that is recessed from a top surface thereof downward, and the placement slot is upwardly exposed from the housing. the dust collecting box is placed into the placement slot downward from above. The frame is provided with a fixed opening in communication with the placement slot. The fixed opening is correspondingly in communication with the dust suction conduit in a fixed manner. The dust collecting box is provided with an opening that is correspondingly in communication with the fixed opening.

In one embodiment, the dust suction apparatus further includes a flexible baffle. The flexible baffle is pivotally connected to the dust collecting box. At least one stopping block is disposed at the fixed opening of the frame. When the dust collecting box is placed in the placement slot, the stopping block urges against the flexible baffle and drives the flexible baffle to rotate, making the opening in an open state.

Compared with the related art, certain embodiments of the present invention use the partition plate to divide an accommodating cavity into the first accommodating cavity and the second accommodating cavity. The dust suction conduit is in communication with the first accommodating cavity, and a slit is formed between the first rotatable brush in the first accommodating cavity and the partition plate. When the intelligent cleaning robot cleans the floor, dirt cleaned by the first rotatable brush is directly sucked into the dust collecting box through the slit, and dirt cleaned by the second rotatable brush enters the slit through the gap between the partition plate and the floor and is then sucked into the dust collecting box. In the structure described above, space of the first accommodating cavity in communication with the dust suction conduit is small, which makes an air flow velocity in the first accommodating cavity high, i.e., an air flow velocity in the slit is high. Therefore, the capability of the intelligent cleaning robot of sucking up dust and crumbs from the floor below the rotatable brushes is enhanced.

These and other aspects of the present invention will become apparent from the following description of the preferred embodiment taken in conjunction with the following drawings, although variations and modifications therein may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

An elastic tube 26 is sleeved over the rigid driving shaft 25, and an elastic material, such as a foam material, is filled between the elastic tube 26 and the rigid driving shaft 25. Multiple blades 27 protrude outward in a radial direction on an outer surface of the elastic tube 26. The height of the blades 27 is H, and the height H of the blades 27 is less than the height of the gap T. The blades 27 are in the form of straight lines and are regularly distributed at intervals on the outer surface of the elastic tube 26, and the blades 27 are integrally formed with the elastic tube 26. In other embodiments, the blades 27 may also be V-shaped and regularly distributed at intervals on the outer surface of the elastic tube 26.

Referring to FIG. 3, the floor brush assembly 20 includes a floor brush protecting cover 28. One end of the floor brush protecting cover 28 is provided with a hinge portion 281, and the hinge portion 281 coordinates with the pivoting portion 213, so that the floor brush protecting cover 28 can rotate relative to the floor brush frame 21 to be open or closed. Another end of the floor brush protecting cover 28 is provided with two snap arms 282, and the snap arm 282 is substantially in a shape of “n.” A flexible end of the snap arm 282 is provided with a protruding portion (not shown in the figure).

Referring to FIG. 5, the floor brush assembly 20 further includes a first motor 29, and the first motor 29 supplies power to the first rotatable brush 23 and the second rotatable brush 24 through a gear drive mechanism (not shown in the figure).

Referring to FIG. 4 and FIG. 6, the dust suction apparatus 30 includes a frame 31 having a box-shaped structure. The frame 31 is located behind the floor brush frame 21 and is fastened in the lower housing 12. The frame 31 is provided with a placement slot 311 that is recessed from a top surface thereof downward. The placement slot 311 is disposed opposite the upper placement opening 111 and is upwardly exposed from the upper housing 11. A front side of the frame 31 is provided with a fixed opening 312, and the fixed opening 312 is in communication with the placement slot 311. At least one stopping block 313 is disposed in the fixed opening 312, and the stopping block 313 partially extends into the placement slot 311. A rear side of the frame 31 is provided with a window 314. The window 314 is also in communication with the placement slot 311. The fixed opening 312 and the window 314 are disposed opposite to each other. A dust collecting box 32 is placed into the placement slot 311 downward from above. A front side and a rear side of the dust collecting box 32 are each provided with an opening 321 and a filter opening 322 correspondingly. The filter opening 322 is in communication with the placement slot 311 through the window 314. The dust suction apparatus 30 further includes a dust suction conduit 33. One end of the dust suction conduit 33 is sleeved in the fixed opening 312, and air from the dust suction conduit 33 can flow to the dust collecting box 32 through the opening 321. The other end of the dust suction conduit 33 is only in communication with the first accommodating cavity 211. A fan 34 is located right behind the filter opening 322, and provides the intelligent cleaning robot 100 with a suction force for sucking up dirt. A flexible baffle 35 is pivotally connected in the dust collecting box 32, and is disposed close to the opening 321. When the dust collecting box 32 is not placed in the placement slot 311, the flexible baffle 35 covers the opening 321 due to the gravity thereof, so that the opening 321 is in a closed state. When the dust collecting box 32 is placed in the placement slot 311, the stopping block 313 pushes the flexible baffle 35 to rotate upward towards the fan 34, so that the opening 321 is in an open state, allowing dirt sucked up by the intelligent cleaning robot 100 to enter the dust collecting box 32 through the opening 321.

Referring to FIG. 2 and FIG. 5, the two side brushes 40 are located on the left and right sides of the bottom of the housing 10 and in front of the first rotatable brush 23. Each side brush 40 has a rotating seat 41, and the rotating seat 41 is installed in the mounting slot 123 in a fitting manner. A bottom surface of the rotating seat 41 and the mounting surface 122 are in a same plane. The bottom surface of the rotating seat 41 protrudes downwards to form a protruding portion (not shown in the figure). At least one bristle body 42 protrudes outward from the periphery of the protruding portion. In this embodiment, multiple bristle bodies 42 are provided. The two side brushes 40 are synchronously linked to the rigid driving shaft 25 of the first rotatable brush 23 through a transmission mechanism (not shown in the figure).

Referring to FIG. 3 and FIG. 6, the driving apparatus 50 includes two driving wheels 51 located on the left and right sides of the bottom of the housing 10, and the driving wheels 51 are located behind the second rotatable brush 24. Each driving wheel 51 is powered by a second motor 52, so as to drive the intelligent cleaning robot 100 to walk.

Referring to FIGS. 5-7, when the intelligent cleaning robot 100 moves in a working area, the power provided by the second motors 52 drive the driving wheels 51 to rotate, thereby driving the intelligent cleaning robot 100 to walk. At the same time, the first motor 29 provides power to drive the first rotatable brush 23, the second rotatable brush 24 and the side brush 40 to rotate, so as to clean dirt. At this time, the rotation of the side brush 41 brings dirt out of the periphery of the housing 10 into an area below the first rotatable brush 23 and the second rotatable brush 24. The first rotatable brush 23 rotates along counter clock wise direction “CC,” which makes the dirt below move towards the slit G upward to enter the dust suction conduit 33. The second rotatable brush 24 rotates along clockwise direction “C,” which makes the dirt below move upward to the slit G through the gap T and then enter the dust suction conduit 33.

In conclusion, certain embodiments of the intelligent cleaning robot 100 of the present invention, among other things, have the following beneficial advantages.

1. The partition plate 22 divides an accommodating cavity into the first accommodating cavity 211 and the second accommodating cavity 212. One end of the dust suction conduit 33 is in communication with the first accommodating cavity 211, and the other end of the dust suction conduit 33 is in communication with the dust collecting box 32. The first rotatable brush 23 in the first accommodating cavity 211 and the partition plate 22 form the slit G. When the intelligent cleaning robot 100 cleans the floor, dirt cleaned by the first rotatable brush 23 is directly sucked into the dust collecting box 32 through the slit G, and dirt cleaned by the second rotatable brush 24 enters the slit G through the gap T below the partition plate 22, and is then sucked into the dust collecting box 3. With the foregoing structure, space of the first accommodating cavity 211 in communication with the dust suction conduit 33 is relatively small, an air flow velocity in the first accommodating cavity 211 is relatively high. In other words, an air flow velocity in the slit G is relatively high, thereby enhancing the capability of the intelligent cleaning robot 100 of sucking up dirt from the floor below the first and second rotatable brushes 23 and 24.

2. The height H of the blades 27 is less than that of the gap T, which ensures that large dirt cleaned by the second rotatable brush 24 can be easily sucked into the slit G through the gap T.

3. The compliance portion 221 is disposed in a manner of leaning to the second rotatable brush 24, and the gap T is formed between the compliance portion 221 and the floor, so that dirt cleaned by the second rotatable brush 24 can be easily sucked into the slit G through the gap T, and then enters the dust collecting box 32. Moreover, it is avoided that dirt enters second accommodating cavity 212 when the second rotatable brush 24 rotates, so that the second accommodating cavity 212 is not blocked and the rotation of the second rotatable brush 24 is not impeded.

4. Because the bottom surface of the rotating seat 41 and the mounting surface 122 are in a same plane, when the side brush 40 rotates, dirt cleaned, such as hair, does not enter the gap between the external side wall of the rotating seat 41 and the mounting slot 123, thereby avoiding impeding the rotation of the side brush 40.
